Abstract
A system for communication between a first computer terminal (1) in a private IP network (7) and a second computer terminal (5) in a public IP network includes a network boundary equipment (3). The communications system further includes a mediation system (2) in the private IP network that is associated with the first terminal (1) and is adapted to make an IP interface available to the second terminal (5), and a control server (4) in the public IP network able to control the mediation system 2 via a communications tunnel (6) through the network boundary equipment (3).
Claims13
A method for communication between a first computer terminal of a private Internet Protocol (IP) network and a second computer terminal of a public IP network, the method comprising:
- initializing a connection, by a mediation system which is associated with the first computer terminal in the private IP network, to a dedicated service port of a control server in the public IP network, the mediation system being separated from the public IP network by a network boundary equipment of the private IP network;
- establishing, by the mediation system, a communications tunnel between the mediation system and the dedicated service port of the control server, through the network boundary equipment;
- receiving at least one port operation request, from the control server, at the mediation system via the communications tunnel established through the network boundary equipment;
- performing, by the mediation system, the at least one requested port operation, resulting in an IP interface of the mediation system which is available to the second computer being connected to an IP interface of the first computer.
A system for communication between a first computer terminal of a private Internet Protocol (IP) network and a second computer terminal of a public IP network, the private IP network comprising network boundary equipment, the system comprising:
- a control server which is associated with the second computer terminal in the public IP network, the control server being configured to perform a port operation at the mediation system via a communications tunnel established through the network boundary equipment;
- and
- a mediation system which is associated with the first computer terminal in the private IP network, and which is configured to initialize a connection to a dedicated service port of the control server in the public IP network, the mediation system being separated from the public IP network by a network boundary equipment of the private IP network,
- wherein the mediation system is configured to establish the communications tunnel between the mediation system and the dedicated service port of the control server, through the network boundary equipment.
